CCC Energy Posted December 9, 2020 Share Posted December 9, 2020 Anyone got any thoughts on the best way to get 4mm or 6mm solar cable to the panel, lets assume you have 20mm BOSAL conduit in the roof, then I guess you have two choices 1. Connect Kopex to the end of the Bosal and come around the roof edge eves to the panel where a nylon cable gland is on the end of the Kopex 2. Drill through the tile and put a Dektite lead panel (needs replacing after 8 years) to a Bosal upright in the roof 3. Other ? Quote Link to comment Share on other sites More sharing options...
Gerrie Posted December 10, 2020 Share Posted December 10, 2020 For me normally the shortest route to prevent long runs of cable. Even if the bosal protrude through a roof tile as long as it is properly secured inside the roof to minimize movement and then properly sealed with a UV resistant sealer at the hole where it exits the tile, than a round galvanized junction box on-top of the roof with a rubber seal in the lid. From there you can direct a flexible conduit or armored cable or whatever is UV resistant to the fusebox and from there again to panels. Going around the eves might present a bit of a hazard as someone doing other maintenance work can put a stepladder against it and damage it, also it might be getting more running water during rain, higher up on rooftop gets a bit less running water.
